Abstract
Spectrophotometric determination of cobalt by flow injection method is described. 2-(5-Bromo-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino) aniline rapidly forms a water-soluble complex with cobalt in <TEX>$NH_3-NH_4Cl$</TEX> buffer solution at pH 10.5. The absorption maxima of this complex is at 545 nm with molar absorptivity of <TEX>$58000L\;mol^{-1}\;cm^{-1}$</TEX>. The calibration curve of cobalt is linear over the range of 0.1 to 0.6ppm and the detection limit is 25ppb. The relative standard deviation is <TEX>${\pm}0.72%$</TEX> for 0.5ppm and the sampling rate is <TEX>$60samples\;hr^{-1}$</TEX>. The interfering effect of some cations and anions was investigated. Ni(II), Cu(II), Fe(III) and <TEX>$CN^-$</TEX> interfered severely. The interfering effect of these matallic ions could be decreased by adding <TEX>$1.0{\times}10^{-3}M$</TEX> EDTA solution to the carrier stream.
